PERFORATlNG-STAM P.

SPECIFICATION forming part of Letters Patent No. 447,089, dated February24, 1891.

Application filed June 2i, 1890. Serial 110,356,180. (No model.)

certain new and useful Improvements in Perforating-Stamps; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates to perforating-stamps and it consists in certainpeculiarities of construotion and combination of parts whereby variousgroups of arbitrarilyselected characters may be accurately determinedand indefinitely reproduced in perforations on bankchecks, bonds, &c.,with absolute certainty, all the characters in each group beingreproduced by a single operation, as will be hereinafter described withreference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a side elevation of my improvedperforating-stamp partly broken away; Fig. 2, a sectional view of thesame on line 2 2 of the preceding figure; Fig. 3, a detail plan view,partly in horizontal section on line 3 3 of Fig. 2 and partly brokenaway; Fig. 4, a detail horizontal-section on line 4 4 of Fig. 1, andFig. 5 a diagram on line 5 5, Fig. 2.

Referring by letter to the drawings, A represents the base of my device,provided with slotted standards B, the latter serving as guides forsliding blocks 0, having squared openings for correspondingly-shapedportions 12 of a shaft D, that forms the bearing for a series of rotaryadjustable polygonal dieplates E, the faces of the die-plates beingprovided with pins 0, arranged to form arbitrarily-selected characters.Each die-plate is provided with a series of apertures d, thatcorrespond'in number to the faces of said die-plate, and each slidingblock has an aperture that corresponds in diameter to those in thedie-plates. The die-plates being rotary adjustable, they are locked intheir adjusted position by means of a rod F, passed through thoseapertures in said die-plates that register with the apertures in thesliding blocks 0, and I prefer to provide the rod with a transversegroove 6 for engagement with a latch f, pivoted to one of the standardsB of the device. This engagement of the groove and latch preventsaccidental displacement of the rod F, and by having the latter ofsufficient length, as shown in Fig. 2, it may be used as a means foractuating the stamp formed by the several die-plates, the latter and thesliding blocks 0 being returned to and held in their normal position bymeans of springs G, connecting arms 9 of the shaft D with the ends of acrossbrace II, that unites the upper ends of the standards B, as bestillustrated in Fig. l. Vhile the rod F may serve the purpose justdescribed, I find it convenient to trunnion a- -shaped lever I in theupper ends of the standards 13 and connect lateral arms 7L ofthis leverwith the ends of the shaft D by means of irregular links J, the shape ofthese links being such as not to interfere with said rod in case thelatter is projected in the path of said links.

Supported on the base A is a bed-plate K, provided with rows of verticalperforations i, parallel to each other in longitudinal and transversedirections, and a recess j in the bed-plate forms a space between saidbase and perforations for the reception of the punched-out material.Hinged to the bedplate K is a frisket comprising a frame L and thinbottom piece M, the latter being provided with parallel rows ofperforations 70, designed to register with those in said bed-plate.Springs N are preferably connected to the standards 13 of the device toimpinge against the frisket, and thereby clamp the latter firmly againstthe material on the bed-plate in position to be perforated. In practiceit will be found of advantage to roughen the opposing faces of thebed-plate and frisket, in order to secure a better hold on the materialto be perforated. In Fig. 1 the frisket is shown in its raised position;but the normal position of said frisket is shown in Figs. 2

and

Adjacent to the pins 0 on the'die-plates I prefer to paint or'otherwi sedisplay arbitrary index-characters, as shown in Fig. 2, and I alsoprefer to have the same characters above and below said pins, this beinga-matter of convenience in the reading of said characters. Thecharacters displayed at any time on those faces of the severaldie-plates that come nearest to and immediately in front of the oper-ICO ator coincide with the characters formed by the pins on those facesof said die-plates immediately above the perforating-point. Consequentlyit is obvious that the operator can readily arrange any desired group ofpin characters by shifting the die-plates until the desired group inregister with the perforatin point is indicated by corresponding paintedcharacters in plain sight. This being done, the die-plates and slidingblocks 0 are locked together by the rod F, and thus the press is set forperforating the group of arbitrarilyselected characters.

A number of the characters on the dieplate at the left of the operatorare preferably representations of valuesas, for instance, the letter Fstands for francs, but all the characters on said die-plate may be suchas fancy or the requirements of a particular business may dictate. Eachof the other die-plates have characters representing the figures 1 to 0,inclusive, and these latter die-plates may have such other characters ordesigns as may be found desirable.

As shown in Fig. 2, the characters displayed on opposite sides of thepins on the faces of die-plates nearest to and immediately in front ofthe operator read F O 5 6 =4: 1, and consequently the pin charactersover the perforating-point are in the same arrangement as shown by thediagram, Fig. 5. characters having been once arranged, the perforatingof the same group may be repeated indefinitely with absolute certaintywithout any rearrangement-of the die-plates, and the latter cannot beshifted either intentionally or otherwise until the locking-rod iswithdrawn.

Attention is called to the fact that by having the perforations in the fisket and bedplate arranged in rows parallel to each other inlongitudinal and transverse directions I do away with the necessity ofhaving to arrange a separate set of perforations for each characterformed by the die-plate pins.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is
